crash_dump: Add vmcore_elf32_check_arch
parse_crash_elf{32|64}_headers will check the headers via the elf_check_arch respectively vmcore_elf64_check_arch macro. The MIPS architecture implements those two macros differently. In order to make the differentiation more explicit, let's introduce an vmcore_elf32_check_arch to allow the archs to overwrite it.
